Tire tread



FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that the tread pattern repeats uniformly throughout the outer surface and shoulder circumference of the tire tread, the diametrically opposite side perspective view being identical thereto;

FIG. 2 is an enlarged fragmentary front elevation view of the tire tread of FIG. 1, the enlarged fragmentary rear elevation being identical thereto;

FIG. 3 is a full front elevation view of the tire tread thereof, the full rear elevation view being identical thereto; and,

FIG. 4 is a full side elevation view of the tire tread thereof, the opposite side elevation view being identical thereto.

The broken line disclosure of the tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design.

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown at the top and bottom edges of FIG. 3. 

The ornamental design for a tire tread, as shown and described.
